Status Epilepticus: Definition, Dangers & Emergency Management

Status epilepticus (SE) is a neurological emergency: continuous seizure activity ≥5 minutes or recurrent seizures without recovery of consciousness between them.

Types

• Convulsive SE: Tonic-clonic (most dangerous).
• Non-convulsive SE: Absence, complex partial, or subtle status—altered consciousness without major motor signs.

Critical Risks

• Neuronal injury: Excitotoxicity, metabolic exhaustion → permanent brain damage.
• Systemic complications: Aspiration, rhabdomyolysis, hyperthermia, lactic acidosis, cardiac arrhythmias.
• SUDEP: Sudden Unexpected Death in Epilepsy risk markedly elevated.
• Mortality: 10–20% short-term; higher in elderly and refractory cases.

Immediate Management (ABCs + Benzodiazepines)

1. Airway, Breathing, Circulation; oxygen, IV access, cardiac monitor.
2. 1st line: IV lorazepam 0.1 mg/kg (max 4 mg) or IM midazolam 10 mg.
3. 2nd line (if SE persists): IV fosphenytoin/phenytoin, valproate, or levetiracetam.
4. 3rd line (refractory SE): Continuous IV anesthetic (midazolam, propofol, pentobarbital) + EEG monitoring.

Time is brain. Treat aggressively per protocol.
